Abstract

Urban power grid is the fundamental facility. Either the lack of internal components’ in the power network or external emergency, such as natural disaster, may lead to an unexpected chain of effects, including paralyzing the power facility and cutting off public services. These incidents could devastate the social stability, and cause huge financial losses. Regarding the precaution principle related to the priority of emergency management, there is the potential risk of losing power and the number of vulnerable facilities will be higher. However, the operation stability will be increased, thus accelerating the responding to external stimuli. The investment decision-making on vulnerabilities of urban power grid infrastructure must take into account the potential risks of losing power, and the input-output index system must be built upon financial, technical, safety feasibility and compatibility. This study applies the CCR model to horizontally compare the efficiencies of investments in the power infrastructure in six districts from SZ city, revealing the vulnerable districts of urban power network infrastructure, thereby that allocation of resources should optimize on the whole, and investment funds in the vulnerable areas of urban power grid infrastructure should increase.
